SPECIFICATION forming part of Letters Patent Ho. 311,689, dated February 3, 1885.

Applicaii n filed June 17, 1894. (No model.)

To crZZ whom it may concern.-

Be it known that I, ANDREW J AOKSON SWEENEY, of Pana, in the county of Christian and State of Illinois, have invented certain new and useful Improvements in Corn-Culti vators, of which the following is a full, clear, and exact description. I

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1, Sheet 1, is a plan view of my iniprovement, partly in section. Fig. 2, Sheet 1, is a sectional side elevation of my improvement, taken through the broken lineac .90. Fig. 1. Fig. 3, Sheet 1, is a side elevation of one of the rotary knives, and showing its bcarin g and the lower part of its standard in sec tion, taken through the line 1 1 Fig. 4. Fig. 4, Sheet 1, is a front elevation of the same. partly in section. Fig. 5, Sheet 2, is a front elevation of the improvement, partly in section, through the line 2 c, Fig. 2.

The object of this invention is to facilitate the cultivation of corn and other crops planted in hills or drills, and also to promote convenience in adjusting, guiding, and controlling cultivators.

The invention consists in the construction and arrangement of parts, as will be hereinafter fully described and claimed.

A represents the whccls,the axle B ofwhich is arched in its middle part to adapt it to pass over plants without injuring them.

To the center of the axle Bis attached the tongue 0, which is strenthened against side strain by the braces D. The forward ends of the braces D are attached to the opposite sides of the tongue 0, and their rear ends are at tached to the end parts of the axle To the end parts of the axle B are attached the lower ends of two standards, E, to the upper ends of which are attached or upon them are formed the ends of the cross-bar F. The middle part of the crossbar F is secured to the arched middle part of the axle B by clamps G or other suitable means.

To the lower side of the horizontal end parts of the axle B are secured by bolts H plates I, which project in front of the said axle, and are perforated for the passage of the knifestandards.

To the forward side of the end parts of the cross-bar F are secured by bolts J theplates K, the lower parts ofwhich are bent forward at right angles and are perforated to receive the knifestandards. The plates I K are slotted to receive the fastening-bolts H J, so that by loosening the nuts of the said bolts the said plates can be adjusted to adjust the knifestandards as may be required.

L are the knife-standards, the upper parts of which are made round, to pass through and turn in the perforations in the angle-plates K. The lower parts of the standards Lare made square, and pass through the perforations of the plates I and through square perforations in the small plates M, placed upon the said plates I, and which have numerous holes formed through them, as shown in Fig. 1, to receive pins or bolts N. The pins N also pass through holes in the plates I to hold the plates M, and with them the standards L,fron1 turning. With this construction, by withdrawing the pins N the plates M and standards L can be turned to adjust the knives to any desired inclination with the rows of plants. The plates M have flanges or bushes 0 formed upon them around the square holes through which the standards L pass, to prevent the corners of the said standards from being worn by the edges of the plates K. The lower ends of the standards L are enlarged, and are perforated to form hubs I, the inner surfaces of which are lined with case-hardened metal, Q, to lessen the friction and wear.

Iithin the lining Qis placed the spindle R, which is perforated to receive the bolt S, which also passes through the cap washers T and through the knives U. The knives U, washers T, and spindles R are rigidly connected with the bolts S, so that the said knives,washers, and spindles will revolve together.

Through the hubs P and linings Qiare formed oil-holes V, which are covered by caps W, hinged to the standards L, to prevent the said oil-holes from becoming choked with dust, so that the spindles R can be readily oiled.

The knives U are made in the form of concaved disks, as shown in Figs. 1, 4, and 5, and may be arranged with their concave sides outward, as shown in Figs. 1 and 5, or with their concave sides inward, according as it is desired to throw soil from or toward the plants.

X are clamping-bars, which are secured to the standards L' at each side of the machine by bolts Y.

To the clamping-bars Xare secured or upon them are formed lugs Z, which are perforated to receive the forked ends of theleversa. The levers c are pivoted to supports b, attached to the sliding plates I, so that all the standards L and their knives U at each side of the ma- 0111111803111 be raised and lowered together.

Upon the supports 11 are formed or to them are attached catch-plates c, with which ongage spring-lever pawls d, connected with the said levers, so that the levers a, standards L, and knives U will be held securely in any position into which they may be adjusted.

To lugs formed upon the middle parts of the forward edges of the plates [are attached the rear ends of the draftchains e, the forward ends of which are attached to a clevis, f, attached to the center of the double-trceg. The doublc-treeg is secured at its center to the tongue 0 by-a bolt, 71, which passes through the said double-tree gand through a slot, 11, in the said tongue 0, so that the draft-strain will come upon the plates I, thus lowering the point of draft attachment and relieving the horses necks of downdraft.

To the'ends of the doubletree g are attached the forward ends of two chains, j, the rear ends of which are attached to the ends of up wardly-projecting armsk, attached to the outer ends of rods Z, rocking in bearings m, attached to the rear sides of the lowcrhorizontal pints of the axle B. 1

' To the inner ends of the rods Z are attached rearwardly projecting arms it, having footrests formed upon or attached to them, so that the rods Z and their arms k n will form bent footlevers. \Vith this construction, by operating the righthand footlever 12 Z10 the machine will be turned to the left, so that the said foot-levers can be used in guiding and turning the machine.

0 is the drivers seat, which is secured to the rear end of the tongue 0 by a bolt, 19, passing through a slot in the said rear end of the tongue 0, so that by loosening the nut of the boltp the seat 0 can be moved forward or back to cause the drivers weight to properly balance the machine. 1 Having thus described my invention, what i I claim as new, and desire to secure by Letters Patent, is

1. v In a cultivator, the combination, with the axle B and the crossbar F, of the slotted plates I K, and their fastening-bolts H J, the standards L, and the concaved rotary knives U, substantially as herein shown and described, whereby the standards and knives upon each side will be securely held, and can be readily adjusted nearer to or farther from the center of the machine, as set forth.

2. In a cultivator, the vertical standard L, having a hub, P, lining 0 within the hub, and the spindle R, adapted to revolve within the lining, in combination with a bolt, S, rigidly connected to the spindle R, the washers T,rigidly connected to the bolt S on opposite sides of the hub, and knife-disk U, rigidly connected to one end of the bolt outsideof one of the washers, substantially as set forth. a

3. In a cultivator, the combination, with the vertical standards L and the plates I, provided with openings through which said standards pass, otthe horizontal clam pi ng-bars X on opposite sides of standards, the bolts S, pass ing through said bars and securingthcm firmly to the standards, and the pivoted levers a, connected at their forward ends to the said bars X, for simultaneouslyraising and lowering the standards, substantially as herein shown and described.

4. Ina cultivator, the combination, with the axle B and the double-tree g, of the bent footlevers consisting of the horizontal rocking bars Z, foot-levers n at the inner ends thereof, and the vertical standards It at the outer ends, and the chains j, connected at their ends to the vertical standards It and the ends ofthe doubletree, whereby the draft may be alternately changed from the. center to the ends of the double-tree for guiding the machine, substantially as set forth.

5. In a cultivator, the combination, with the axle B and thecrossbar F, of the laterallyadjuslable plates I K, secured, respectively, to the axle and cross-bar, vertical knife standards L, passing through openings in said plates and secured together by bars, notched rack-bars b, secured to the plates I, pawl-levers a, pivoted to said rack-bars with their short arms extending to the standards L, for

operating them, whereby when said knifestandards are adjusted horizontally by means of plates I K the relative position of levers a thereto will not be changed, substantially as set forth.
